Biofilm dental, un reservorio para helicobacter pylori en pacientes con gastritis crónica

Abstract

Objective: To determine the prevalence of helicobacter pylori in dental biofilm in patients with chronic gastritis in the gastroenterology service of the Hospital Maria Auxiliadora. Methods: A descriptive crosssectional observational study was carried out, working with a population of patients treated in 1 calendar year, of which only 100 patients met inclusion and exclusion criteria. A collection was made for the variables age, sex, helicobacter pylori in dental biofilm and helicobacter pylori in gastric mucosa biopsy. The relative frequency of Helicobacter Pylori in dental biofilm in patients with chronic gastritis was calculated and an exploratory chi2-square test was performed for helicobacter in dental biofilm and helicobacter in gastric mucosa biopsy. Results: A prevalence of helicobacter pylori in dental biofilm of 66% was detected in patients with chronic gastritis, in turn 48% of the total of this group had a positive helicobacter pylori in gastric mucosa biopsy. Of the patients positive for helicobacter pylori in gastric mucosa, 83.33% showed positivity in dental biofilm. An association was found for the variables helicobacter pylori in dental biofilm and helicobacter pylori in gastric mucosa biopsy with a value of p = 0.002. Conclusion: A high prevalence of helicobacter pylori was found in dental biofilm of patients with chronic gastritis and an association between dental biofilm and gastric mucosa biopsy for helicobacter pylori.
